NHTSA Complaint #11709664 — 2018 TESLA MODEL 3

I purchased this car new in 2018 and recently replaced the front lateral suspension arm due to worn bushings. During the process, I discovered that one of the 14 mm bolt threads on the right side of the suspension arm had a helicoil inserted. While removal was straightforward, reinstalling the bolt proved difficult. I spent several hours reattaching it to the new suspension arm, but did not apply full torque, as I was concerned about damaging the helicoil or stripping the thread. My main concern is that the factory has stripped the original thread and used a helicoil instead of replacing the affected part. Although the repair has held so far, I am unsure if this is a safe long-term solution, as the helicoil could fail while driving. I contacted Tesla, who advised me to visit their service center. At the Centinela location in Los Angeles, the supervisor informed me that, since the warranty has expired, they can only perform a visual inspection.
